The Seven Colossi

The Seven Colossi (七つの最強種, Nanatsu no Saikyō-shu) are seven unique secret monsters, which can spawn anywhere at anytime, who won't respawn when killed. They are designed to be nearly unbeatable and can only be defeated by triggering their unique quests. Once a Colossi is defeated, the world story moves and opens new areas.
